Optimization of polyphenols separation from Pomegranate seeds by macroporous resins and study on antioxidant activity of the extraction

This paper utilized the pomegranate seeds,the processing waste,from Anhui Huaiyuan as experimental materials to establish a macroporous resin purification methods of polyphenol:AB -8 was selected as the experimental resin. The flow rate for absorption was 0.75 mL/min and the elution rate was 0.5 mL/min. After purified by the resin the total polyphenol content increased from 53.13% to 78.80%; adsorption process was inferred to be the monolayer adsorption,i.e. Langmiur adsorption. Equation was obtained as y= 0.01211 +0.02086x,R2 =0.9977; the theoretical maximum adsorption capacity of adsorbed total polyphenol content was 82.56 mg/g.
